How are evolution and allele frequency connected?

An example of macroevolution is the evolution of a new species. One mechanism that drives evolution is natural selection, which is a process that increases the frequency of advantageous alleles in a population. Natural selection results in organisms that are more likely to survive and reproduce.

evolution is the process that catalyzes genetic changes within a population of organisms. so evolutionary change can't occur without changes in allele frequency while a change in allele frequency is an indication that evolution is occurring

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.
